Fix neuron non-interactivity after undo operation

- Undoing a change to a neuron renders it non-interactive. Updating a neuron via the TiledMicroscopeRestClient returns a TmNeuronMetadata object where the annotations have a null neuron Id. This causes the vertex hover action to subsequently fail. Fixed by reinitializing the annotation neuron Ids during update.
